Be it known that I, OSCAR F. Mossnnno, a citizen of the-United States, residing at Fitchburg, in the county of Worcester andCom- 5 monwealth of Massachusetts, have invented new and useful Improvements in Revolving' Firearms, of Which-the following is a specification, accompanied by drawings forming'n. part of the Same, in which-4.

Figure 1 represents a side view of a revolving irearxn embodying' my invention... Fig.

2 is a, top view of 'the saine witlithe cylindercase opened and the cylinder released. lFig, 3 is a horizontal sectional View through the i 5 cylinder and Athe swinging arln on-wliich the cylinder iS mounted. Fig. 4l is atransvorse sectionalviewy through .the cylinder..

Similar letters refer to similar paris in the different iignres. l

2e My present invention relates to that class of revolving lireerms in which the cylinder is; Journaled on an' arrn hinged below1 the barrel in. order toallow the cylinder to be swung to one side of the frame; and it has for its z5 objects to improve the construction of the hinged cylinder-carrying arm and to-pro'vide ineens for incloeing the cylinder and holding; it in its firing position, and these objects are accomplished by means offthe construction 3o and arrangement of parts as hereinafter de,- scrlbed, the novel features being set forth in the annexed claims1 Referring to theaocompanying drawings, A denotesA the frame, B theb'arrel, and C the 35 cylindeiyof .a revolving firearm. The c vlinder C is journaled upon the end of an arm. D, which is lpivoted at D'beneath the barrel,

and in the presentinstance to the under sidel of the barrel. A bar yE is pivoted et one end 4o to the arm D, with its opposite end bearing against the frame A. A. spiral spring F, held in a. recess in the arm i), hns one of its ends bearing against the oar E and its opposite end bearing avainst a Screw F', held in the. D

45 arm D, so' thatthe tension of the Spring F is exerted to rock the erin D onits pivot D and swing the cylinder to one side of the frame, es shown in Figs. 2 and The pressureof the spring F is received near the end of the bar E, whichv is pivoted to the Swinging erin 5o D, While the `opposite end of the bar il is held freni movement by its contact With the iiiied frame of the' firearm, thereby allowing the erin. D, bar E, and Spring F to be nssembled prior toy pivotally nttechingthe arm .D tothe barrel, and anyelight variation in the rele-- v tive position of the pivot of theerm' doce -not affect the operation of the device, as thejpiv.-

.etal connectionof the ber-E is cerried'bjgr-tire arm D. The arm: D is' provided at its free end with a-cylindrical bearing for the oyiin der C, Whieh is held in plaoeby menne ,of t collar Q', projecting from the end of thecyl inder and having agro'ove Cwhieii is geged by the .hooked end of a latch G, pivoted 5 in 'a lug;v Don'the arm D and heid e ment Vwiththe groove C* by a spring G ing in the -arm D is it barH, which. is ,our .vided with eknob H', extending through a, slot H2 in ehe armi). The end of t'ne bar E is in contr-.ct with. the end of an extractor-- Spindle H3, which carries an entrzictenliead il. and is held in' its normal position *by e spiral Springv H5, surrounding vthe redo-sed shank o the spindle H3, with one of itscnds v bearing againsta collar H7 on the extracten spindle. v

fVhen the'cylinder Cis held in its norma-l or firing position in the frame A, itisincesed by the covers-I and J.. The cover l' E is et Se tacked by'scr'ews 1/ to the iframe, and 'the oever J is hinged to the frame at J and' its ripper edge is provided with. the iiange J 2, which is engegedby; the lip Igel' a latch-plate K, pivoted et K2 to the frame sind held in engage 85 ment' with the flange ofthe cover J by means of a Smell blade-spring K3', interposed between `the rigid` frame of the firearm and the edge' K4 of the latch-plate. In order 'to 'unlnteh the cover J and. release the cylinden 9e C, the edge K4 of the'latch-plete is depressed, permitting the tension of the spring' il to swing the cylinder C to one side of the freine and push open the cover J, as shown 1n 0 Closing the cover J crowds Ithecj.inder 95 vinto vits normal or iiring position holds by the Contact of the edge J3 oi 'the cover it J against the lug D, So that the lungedcovor 3S Jeeting from'seid erin, and woover for the .l serves as e let-oh io maintain the eyiinde'r i in its normal or iirin` position.

'and the head lmeintziiniil in redistriitionr The extraetonspin'ile lli next the head Hi is polygonal in orosssection and siidee in :t similar polygonal hole in the cylinder, es shown at H8, and 4.-, by which the spindle H3 isJheld from tunning` in the eyiinfler with the chambers ofthe cylinder.

W het I oleiin as my intention, and desire to secure by Letters Pntent, ie f l. The combination W' li the fre-.ine and om rel of a revolving: firearm, oi' an erin pivoted at one end beneath the barrel, e cylinder anni ried by the free end of saiderin, e. rigid lier pivoted ntr one end to seid cylinder-min with its free end lieztring'egainst the frame, ende spring between said bnr end said cylindrelarmto separate the same, substnntielly as deu 2. The combination with the freine and han rel of e revolvlnfy firearm, oit am erm pivoted at one end to the'bnrre, n oyiinderofirried by ksud capable of rotating on the free end, of

seid arenev rigid ber pivoted et one end to seid arm, a spiral spring heldin seid arm ywith one end bearing against said bar; to crowd ,away from seid arm, and n screw held in the arm and bearing againstthe apposite end of said spiral spring", substantially :is described.

, Theeomhinetion with the freine and the bmrei of a revolving iireerro, of en erin pivoted n beneath seid barrei, e cylinder jonrnaledon the endof said erm, e npringepplied to said arm to swing iten its pivot, a lugproeylinderpivoted on seid freine and hearing against seid lugte hold the cylinderin itsy substautially es de ne nel. i

index: out of its normal firing position, a cover for said cylinder hinged :it one end to said freine end bearing against seid erin to hold the cylinder in ite firing position and ineens for holding,r said Cover against the pressureof kthe oyliuder, substantially es deseriheil.

5. The combination with the Emme and. bztrrel of a revolving firearm, of e rotating Cylinder held in said. frame and in its normal po'- sition of firing, :t @over inoiosing,r one sido of seid eylinder, smid @over being hinged at its lower edge to seid freine and having a lip at its upper edge, rocking plete forming the vtop plate of the fraineendhinged beneath iis center sind e spring toeerry one 'edge of seid plate into engagement with said lip with the opposite odge of--nniil ypinto forming e thumb-piene hywhioh it is rookedftorelesse Said oever, substantially es described.
